RELATED APPLICATIONS

This application is a continuation and claims priority of U.S. patent application Ser. No. 14/956,224, entitled “On Demand Passwords,” by Chhabra et al, filed on Dec. 1, 2015, which claims priority of U.S. Provisional Application No. 62/133,189, entitled “On Demand Passwords,” by Chhabra et al., filed on Mar. 13, 2015, each of which is incorporated herein by reference in its entirety and for all purposes.

BACKGROUND

The disclosed embodiments relate generally to computer-implemented methods and apparatus for implementing on demand system-generated passwords associated with user accounts.

To gain access to resources of a computer system, an individual is often required to complete a login procedure. In some instances, the computer system may include a remote computer. Resources offered by a computer system may include, for example, data, applications, or various services offered by the computer system.

During the login process, the computer system typically identifies and authenticates an individual. Generally, authentication is performed using a password submitted by the individual. For example, a web site may provide a login page that enables the individual to submit a password to successfully log in to the web site.

A password is typically a word or string of characters used for user authentication to prove identity or access approval to gain access to a resource offered by a computer system. Generally, an individual selects the password that the computer system will use to authenticate the individual during subsequent login processes.

SUMMARY

In one embodiment, a user password may be received in relation to a user identifier, wherein the user identifier and user password are associated with a user account. A request to opt-in to use of system-generated passwords instead of the user password may be received. A substitute password for the user account may be generated and provided.

In another embodiment, a device comprising a processor and a memory is configured to perform one or more of the above described method operations. In another embodiment, a computer readable storage medium having computer program instructions stored thereon are arranged to perform one or more of the above described method operations.

The disclosed embodiments may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the disclosure. The Detailed Description is not intended as an extensive or detailed discussion of known concepts, and as such, details that are known generally to those of ordinary skill in the relevant art may have been omitted or may be handled in summary fashion

Subject matter will now be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific example embodiments. Subject matter may, however, be embodied in a variety of different forms and, therefore, covered or claimed subject matter is intended to be construed as not being limited to any example embodiments set forth herein; example embodiments are provided merely to be illustrative. Likewise, a reasonably broad scope for claimed or covered subject matter is intended. Among other things, for example, subject matter may be embodied as methods, devices, components, or systems. Accordingly, embodiments may, for example, take the form of hardware, software, firmware or any combination thereof (other than software per se). The following detailed description is, therefore, not intended to be taken in a limiting sense.

Throughout the specification and claims, terms may have nuanced meanings suggested or implied in context beyond an explicitly stated meaning. Likewise, the phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment and the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment. It is intended, for example, that claimed subject matter include combinations of example embodiments in whole or in part.

In general, terminology may be understood at least in part from usage in context. For example, terms, such as “and”, “or”, or “and/or,” as used herein may include a variety of meanings that may depend at least in part upon the context in which such terms are used. Typically, “or” if used to associate a list, such as A, B or C, is intended to mean A, B, and C, here used in the inclusive sense, as well as A, B or C, here used in the exclusive sense. In addition, the term “one or more” as used herein, depending at least in part upon context, may be used to describe any feature, structure, or characteristic in a singular sense or may be used to describe combinations of features, structures or characteristics in a plural sense. Similarly, terms, such as “a,” “an,” or “the,” again, may be understood to convey a singular usage or to convey a plural usage, depending at least in part upon context. In addition, the term “based on” may be understood as not necessarily intended to convey an exclusive set of factors and may, instead, allow for existence of additional factors not necessarily expressly described, again, depending at least in part on context.

The disclosed embodiments support the generation and use of on demand system-generated passwords for user accounts. More particularly, an on demand password feature may be enabled or disabled in response to a user action. In addition, an on demand system-generated password may be requested in response to a user action.

In some embodiments, a user action may include interaction with a system-provided indication (e.g., menu, icon, button, or hypertext link) or submission of a user-initiated request. For example, the user action may include selecting or activating an icon, button, or hypertext link using an input device (e.g., clicking on the indication using a mouse) or interacting with a touch screen of a client device (e.g., tapping on the system provided indication). As another example, the user action may include using a voice command or sending a short message service (sms) message.

According to various embodiments, a computer system may support the use of on demand system generated passwords. More particularly, the system may provide an option to enroll in on demand password services to users having user accounts with the system. In some embodiments, on demand password services may be provided as an option for all user accounts. In other embodiments, the ability to opt-in to on demand password services may be made available to a subset of user accounts maintained by the system.

Typically, an individual may submit a user password in association with a user identifier at the time that a user account is established. In addition, the user password may be changed upon submission of a new user password to the system. For example, a user password may be submitted to the system in association with the user identifier via a graphical user interface.

To obtain access to the user account, a user may log in to the user account by submitting his or her user identifier and user password via a graphical user interface. Once logged in to the user account, the user may access information in the user account, access content or services provided by the web site, or receive various services such as personalized content from the system. In many instances, the user account provides access to valuable personal information such as credit card numbers or the user's social security number.

Individuals often have multiple user accounts across a number of systems. For example, these systems may be associated with phone companies, banks, email systems, etc. As a result, the individuals have to keep track of the passwords associated with all of their user accounts. To make it easier to remember their passwords, individuals often re-use the same password across various systems.

Today, individuals have the ability to access their accounts from different locations. More particularly, most individuals own mobile devices such as tablets, laptops, or cellular phones, increasing the likelihood that they will access unsecured wireless networks. In addition, individuals may access their accounts from computing devices other than their own when they are not at home. For example, individuals might access their friends' computing devices or airport kiosks when they are traveling. Therefore, there are many opportunities for user information submitted during the login process to be compromised.

In the event that a hacker has intercepted or captured the username and password of a user during the login process, they may gain access to valuable personal information of the user via the corresponding user account. In addition, where the user has used the same password for other accounts, the security of his or her other accounts may also be comprised.

Some systems offer additional security by using a two-tier authentication operation. For example, once a user has submitted their user identifier and password, such systems may generate and provide a further code via email to be submitted by the user to successfully log in to their user account. While such systems may provide additional security, this is a more time-consuming process. As a result, the user may be less motivated to return to access their account to use the system. Furthermore, the user still has to keep track of their password to successfully complete the log in process. Accordingly, there fails to be a secure mechanism that enables users to efficiently log in to their accounts that eliminates the need for users to remember their passwords for their accounts.

The disclosed embodiments support the use of system generated passwords, providing users an efficient and secure mechanism for accessing their accounts without the need to remember passwords for their accounts. Examples of systems and methods for implementing the disclosed embodiments will be described in further detail below.

Example System

FIG. 1 is a diagram illustrating an example system in which various embodiments may be implemented. As shown in FIG. 1, the system may include one or more servers 102. For example, the servers 102 may be associated with a web site that provides a variety of services to its users. More particularly, the server(s) 102 may include a web server, search server, and/or content server.

In accordance with various embodiments, users may access various services offered by the computer system by logging in to their user accounts. Such services may include on demand password services that support the implementation of on demand system-generated passwords. Various methods of providing various on demand password services will be described in further detail below.

In some embodiments, the server(s) 102 may provide services such as targeted content to users of the web site. A content server may store content for presentation to users. For example, a content server may store web pages available on the Internet or data gathered via the Internet. As another example, a content server may be an “ad server” that stores online advertisements for presentation to users. “Ad serving” refers to methods used to place online advertisements on websites, in applications, or other places where users are more likely to see them, such as during an online session.

As shown in FIG. 1, a plurality of clients 106, 108, 110 may log in to their user accounts via the web site to access their accounts, purchase products, or access/receive various services offered to account holders by the web site. Such services may include on demand password services. In some embodiments, the services may include the transmission of personalized content to the clients 106, 108, 110. In other embodiments, the services may include email or other messaging services.

Services may be provided to the clients 106, 108, 110 via applications implemented by the servers 102 and/or the clients 106, 108, 110. The clients 106, 108, 110 may access a web service, for example, on a web server via network 104 using a graphical user interface. In some embodiments, the clients 106, 108, 110 may access a search application on a search server via network 104.

The network 104 may take any suitable form, such as a wide area network or Internet and/or one or more local area networks (LAN's). The network 104 may include any suitable number and type of devices, e.g., routers and switches, for forwarding search or web object requests from each client to the search or web application and search or web results back to the requesting clients.

The disclosed embodiments may also be practiced in a wide variety of network environments (represented by network 104) including, for example, TCP/IP-based networks, telecommunications networks, wireless networks, etc. In addition, computer program instructions with which various embodiments may be implemented may be stored in any type of computer-readable media, and may be executed according to a variety of computing models including a client/server model, a peer-to-peer model, on a stand-alone computing device, or according to a distributed computing model in which various of the functionalities described herein may be effected or employed at different locations.

A system supporting various on demand password services may be implemented on any number of servers although only a single server 102 is illustrated for clarity. Various embodiments disclosed herein may be implemented via the server 102 and/or the clients 106, 108, 110. For example, various features may be implemented via a web browser and/or application on the clients 106, 108, 110. The disclosed embodiments may be implemented via software and/or hardware.

As will be described in further detail below, the server(s) 102 may provide on demand password services to users including the generation and transmission of on demand system-generated passwords. More particularly, on demand password services may enable users to opt-in to use on demand system-generated passwords instead of their current user password. In addition, on demand password services may include the generation and transmission of system-generated passwords by the server 102 to the clients 106, 108, 110 on an on demand basis in response to requests, which may be received from the clients 106, 108, 110 or other devices.

Users that are members of the web site, access content or other services of the web site, or receive services such as personalized content from the web site may have user accounts that are maintained by the system. In accordance with various embodiments, the server(s) 102 may have access to one or more databases into which account information is retained for each of a plurality of user accounts. The databases may be retained in one or more memories 118 that are coupled to the server 102.

The account information pertaining to a user account may include a user identifier. The user identifier may uniquely identify an account owner (e.g., user) within the system. For example, the user identifier may include a sequence of alphanumeric characters such as a social security number, a phone number, a family name (e.g., Lovlesh Chhabra), a username (e.g., Lovlesh408), or an email address. In accordance with various embodiments, the user identifier is a username that corresponds to an email address associated with the user account. In other embodiments, the user identifier may be determined using other mechanisms. For example, a user may be identified using biometric authentication methods such as a deoxyribonucleic acid (DNA), retina scan, finger print recognition, or facial recognition. As another example, a user may be identified using a possession factor device such as a universal serial bus (USB) security token, near field communication (NFC) device, or smart card.

In addition, the account information may include one or more passwords. More particularly, the account information may include a user password previously established by a user and/or an on demand password. In addition, the account information may indicate whether on demand password services are active (e.g., as a result of opt-in by a user). In other words, the account information may indicate whether a user specified user password and/or on demand password is currently active. The account information may also indicate the time that the last on demand password was requested, generated, transmitted, or otherwise activated. In addition, the account information may indicate the amount of time that an active on demand password remains active.

In accordance with various embodiments, the account information may also include device information pertaining to the client device(s) previously accessed in association with the user account. For example, the device information may include an IP address, MAC address, browser identifier, and/or geographic location from which the corresponding client device was accessed. The account information may also indicate the number of times or frequency with which the devices or corresponding locations were accessed in association with the user account.

In some embodiments, the account information may further include personal information such as demographic information (e.g., birth date, age, occupation, and/or gender) and/or geographic information (e.g., residence address, work address, zip code, and/or area code). The account information may also include credit card information, enabling account owners to be charged for various products or services offered by the web site.

In addition, each time a user performs online activities such as logging in to the web site, opting in to use on demand password services, submitting a password request, performing a search, clicking on a web page or an advertisement, or purchasing goods or services, information regarding such activity or activities may be retained in user logs. For instance, the user data that is retained in the user logs may indicate the identity of web sites visited, identity of ads that have been selected (e.g., clicked on), client device information (e.g., browser identifier, IP address, and/or MAC address), geographic location of the client device, and/or a timestamp.

FIG. 2 is a process flow diagram illustrating an example method of implementing on demand system-generated passwords. As shown in FIG. 2, the system may receive a user password in relation to a user identifier associated with a user account at 202. More particularly, the user password may be submitted to the system via a graphical user interface presented via a web page. The user may also enter the user identifier in a corresponding input box of the graphical user interface. Alternatively, the user identifier or portion thereof may be presented in the corresponding input box of the graphical user interface without receiving input from the user. For example, the user password may be submitted via a login page that displays the user identifier or portion thereof.

Once a successful login process is completed, access to the user account may be provided. For example, at least a portion of the account information associated with the user account may be modified. In addition, the system may provide a variety of services to a client device via which the user password was submitted to the system in relation to the user identifier. For example, personalized services, which may include content such as news articles or advertisements, may be provided to the client device.

The user may remain signed in to his or her user account for future sessions. Alternatively, the system may log the user out of his or her user account to increase the security associated with on demand password services provided by the system. In one embodiment, the system default is to keep the user signed in. In another embodiment, the system default is to keep the user signed out. The user may modify the system default, as desired.

According to various embodiments, a user may opt in or out of the use of on demand system-generated passwords. For example, an on demand password option may be selected by submitting an opt-in request.

The system may receive a request to opt-in to use of system-generated passwords instead of the current user password at 204. More particularly, an opt-in option may be accessed by the user via a particular web page of the web site. In some embodiments, a graphical user interface may present one or more selectable options to the user, enabling the user to opt-in or opt-out of the use of on demand system-generated passwords. For example, each of the selectable options may be accessed or presented via a menu, icon, button, hypertext link, or other selectable input feature.

In some embodiments, the user may indicate the mechanism by which that they would like to receive system generated passwords and associated messages. For example, the user may indicate by performing a user action (e.g., clicking on one of a set of available options) that they would like to receive system generated passwords via text or email. In other embodiments, the system may support a single mechanism (e.g., either email or sms messages) via which the user may receive system generated passwords and/or associated messages.

In addition, in accordance with various embodiments, the user may submit specific contact information via which the user would like to receive on demand passwords in conjunction with opting in to use system-generated passwords. For example, the user may enter a mobile phone number at the time of opting in to use on demand passwords. Thus, the account information maintained by the system may include specific contact information (e.g., a mobile phone number) that is used for the transmission of on demand system generated passwords to the owner of the user account, as well as general contact information (e.g., an email address). The specific contact information may also be used for the transmission of additional messages pertaining to system-generated passwords to the owner of the user account. By using specific information rather than general contact information, the system may reduce the likelihood that other individuals will capture or intercept system-generated passwords that have been transmitted by the system.

In some embodiments, the system may obtain confirmation of the opt-in request prior to enabling (e.g., activating) on demand password use for the user account and/or disabling the use of the current user password for the user account. More particularly, the system may transmit a notification of the opt-in request using contact information associated with the user account. An account owner may approve or decline the opt-in request for the user account.

Upon receiving the request to opt-in to use of system-generated passwords or a subsequent confirmation of the request by the account owner, the system may update the account information pertaining to the user account such that the user account is not accessible via the current user password. For example, the system may set an opt-in flag in the user account information to indicate that the user has opted-in to receive system-generated passwords. In some embodiments, the system may delete the user password from the account information so that it can no longer be used to access the user account. In other embodiments, the system may deactivate the user password so that the user account cannot be accessed using the user password during the time that the user is opted-in to use on demand system-generated passwords. Deactivation of the user password may be performed, for example, by setting the opt-in flag in the account information associated with the user account.

The system may generate and provide passwords on demand. In accordance with various embodiments, an on demand password may be requested by a user for a user account by submitting a password request. A password request may be submitted to the system via user interaction with a system-generated indication such as a button, icon, or hypertext link. For example, such an indication may be presented via a web page, sms message, or email message. Alternatively, the password request may be transmitted upon initiation of the user. Example mechanisms for submitting a password request include, but are not limited to, interaction with an input device or touch screen of a mobile device. In some embodiments, the previously received request to opt in to use of system generated passwords may serve as a password request.

A password request may be submitted while a previous password for the user account is still active. In addition, a password request may be submitted after the previous password for the user account has expired. In some embodiments, this may be accomplished by submitting the previous expired password to request a new on demand password from the system. In other embodiments, after an on demand password has expired, the system defaults to use of a previously deactivated user password that was active at the time of submission of an opt-in request.

A password request to initiate on demand password generation may be received via various client devices and locations. Thus, in accordance with various embodiments, the system may determine whether a password request was received from the owner of the user account. Such verification may be performed using the account information and/or other information such as that pertaining to the client device that sent the password request. The information pertaining to the client device may include, for example, a geographic location of the client device, Internet Protocol (IP) address of the client device, web browser, and/or Media Access Control (MAC) address of the client device. For example, if the owner of the user account has previously logged in via the same client device (e.g., IP address and/or MAC address), the system may determine that the password has been received from the owner of the user account.

In some implementations, the system limits the number of password requests that may be submitted in association with a user account within a period of time (e.g., minutes, hours, or days). For example, the system may limit the number of password requests that may be submitted in association with the user account to 10 requests within a 24 hour period. The system may impose this limit in situations where the system is not confident that password requests are being received from the owner of the user account. More particularly, the system may determine whether a password request is received from a device and/or location via which the user account has previously been accessed (e.g., via log in or via password requests). For example, the system may determine whether it recognizes the Internet Protocol (IP) address, Media Access Control (MAC) address, web browser, and/or geographic location of the device in association with the user account. Where the system recognizes the geographic location as being one that the account owner frequently visits, the system may choose not to impose this limit. In this manner, the system may increase the security associated with the transmission and use of on demand passwords. Furthermore, the system may reduce the likelihood that an individual abuses the use of password requests to the detriment of the account owner. For example, where the system sends a notification in response to each password request, this may become irritating to an account owner who has shared their password with another individual.

The system may transmit a notification message to an owner of the user account via the user contact information (e.g., general contact information or password-specific contact information). For example, the notification message may include a push notification, flash notification, sms message, an email, a vibration of their mobile device, or a sound (e.g., beep) transmitted via their mobile device. In some instances, a notification message may serve to notify the owner of the account that they have opted in to use system-generated passwords instead of their current user password, thereby informing them their account will no longer be accessible via their user password. In other instances, a notification may serve to notify the owner of the account that the system has received an opt-in request, and may request further confirmation by the owner of the account of the intent of the account owner to opt-in to use of system-generated passwords instead of their current user password. The account owner may decline or approve an opt-in request. For example, the notification message may include a code that the user may use to confirm that they have received the notification and approve of the opt-in request. In yet other instances, a notification message may notify the owner of the account that a password request has been received. In some embodiments, the notification message may include the pertinent contact information for confirmation by the owner of the user account.

The system may wait to proceed with updating account information and/or on demand password generation until it receives a confirmation from the owner of the user account in response to a notification message sent by the system. More particularly, the system may obtain confirmation from the owner of the user account that the account owner has received the notification and, therefore, the contact information (e.g., previously provided in association with opting in to use system-generated passwords) for on demand password generation is correct. In some instances, the system may obtain confirmation from the owner of the account that they would like to opt in to receive system-generated passwords before updating the account information to deactivate or delete the user password. For example, the system may send a sms message to a mobile phone number specified in the account information to confirm that the owner of the user account is in possession of the mobile device having the mobile phone number. Confirmation may be received via a user action such as sending a reply sms message, clicking on a hypertext link provided in a web page or provided in an email message, providing a code via a web page or other suitable mechanism, or interacting with a touch screen (e.g., tapping the screen) of the mobile device.

For example, the system may transmit a push notification of receipt of an opt-in request for use of on demand password services to a mobile device of the account owner. The account owner may tap a touch-screen display of their mobile device. The mobile device may then present a web page including a graphical user interface that enables the user to approve or decline the request to which the notification pertains. The user may approve the request, for example, by submitting a code (received in the notification) via the graphical user interface.

The system may generate and transmit a newly generated substitute password for use in accessing the user account or associated services and update the account information to include the newly generated password, as will be described in further detail below. More particularly, the system may generate a substitute password for the user account, transmit the substitute password, and/or update the account information with the substitute password after or in response to one or more of the following: an opt-in to the use of system-generated passwords for the user account, receiving a password request for the user account, receiving a confirmation from the owner of the user account, and/or verification by the system that a password request has been received from the owner of the user account.

The system may generate a substitute password for the user account at 206. The substitute password may be generated using a password generator. More particularly, the password generator may randomly select a sequence of alphanumeric characters. For example, the system may use a random number generator. The system may store the newly generated substitute password in the account information corresponding to the user account such that the substitute password may be used instead of the current (e.g., prior or most recent) user password. The user account and associated services may subsequently be accessed via the substitute password. In accordance with various embodiments, the substitute password may be generated in response to receiving a password request such as that described above.

In some embodiments, the system may generate the substitute password based, at least in part, on the likelihood that the password request was received from the owner of the user account. Where it is unlikely that the password was received from the owner of the user account, there is greater concern that the password is a malicious attack by an individual attempting to impersonate the owner of a user account (e.g., using the IP address, email address, or mobile phone number associated with the user account). In these instances, the system may generate a substitute password of greater length and/or complexity to reduce the chance that hackers will be able to accurately identify the substitute password (which will serve as the new user password) and gain access to the user account. Alternatively, where it is likely that the password request was received from the owner of the user account, the system may generate a substitute password of shorter length and/or complexity.

The likelihood that the password request was received from the owner of the user account may be ascertained by a decision engine of the system using the account information, the number of accounts associated with the client device, and/or other information such as that pertaining to the client device that sent the password request. Thus, the decision engine may determine whether providing a substitute password in response to the password request would present a security risk. For example, if the account owner has not previously logged in via the same client device (e.g., IP address and/or MAC address) or geographic location, the decision engine may determine that it is less likely that the password request was received from the owner of the user account. As another example, where the decision engine ascertains that the client device that sent the password request has at least a threshold number of system accounts, the decision engine may determine that responding to the password request with a substitute password would result in a risky log in. In this manner, a decision engine may balance security against the convenience of the user.

The system may provide the substitute password at 208. The system may transmit the substitute password via the user contact information associated with the user account. For example, the substitute password may be transmitted via email, push notification, or sms message. As described above, in some implementations, the contact information via which the substitute password is transmitted may be specified or selected by the user in conjunction with opting in to receiving system-generated passwords. Alternatively, the substitute password may be transmitted via general contact information (e.g., an email address, mobile phone number, etc.) maintained in the account information associated with the user account.

In accordance with various embodiments, the substitute password may be a temporary password that is valid for a particular period of time (e.g., minutes or hours) after generating or providing the substitute password. For example, the system may be configured with the particular period of time. As a result, the substitute password may no longer be valid after expiration of the period of time. In one embodiment, the substitute password may be used to log in to the user account any number of times during the period of time. In another embodiment, the substitute password may be used a limited number of times during the time period. The system may deactivate the substitute password upon expiration of the period of time (e.g., by deleting the substitute password from account information or unsetting a corresponding flag). Alternatively, the system may determine whether the period of time has passed upon receiving the user identifier and substitute (new) password.

Once the system has transmitted the substitute password, the user may use the substitute password to log in to the user account. In some embodiments, the user may submit the substitute password (new user password) via a web page that is presented after submission of the password request. In other embodiments, the user may submit the substitute password via a login web page. More particularly, the login web page may be accessed via the client device from which the on demand password was requested or another client device. The user identifier may be entered by the user. Alternatively, the user identifier or portion thereof may be presented by the system in the login web page (e.g. upon recognition of the client device by the system). Therefore, the user may log in to the user account using the substitute password via the client device or another client device.

Upon receiving the substitute password in association with the user identifier for the user account, the system may determine whether the substitute password is still active. For example, the system may ascertain whether the substitute password that has been submitted matches that in the account information for the user account. The system may provide access to the user account and associated services according to whether the substitute password is still active. For example, if the period of time has expired, the system may deny access to the user account and associated services. By limiting the period of time during which the substitute period is active, the system may provide additional security associated with the use of system-generated passwords.

The system may perform authentication for the session using the substitute password that has been entered in association with the user identifier. After the login is successfully completed, the system may provide access to the user account and any associated services (e.g., without receiving a further access code). Accordingly, the disclosed embodiments may support the authentication during login to a user account using a single factor of authentication.

The user may subsequently choose to opt out of the use of on demand system-generated passwords. In some embodiments, the system may reactivate a previously deactivated password (e.g., by modifying a corresponding flag in the account information). In this manner, the system may enable the user to use their previous user password. The system may present a success dialog and/or transmit a notification to inform the user that they have successfully opted out of using system-generated passwords.

FIGS. 3A-3H are screen shots illustrating example graphical user interfaces that may be presented to facilitate log in to a user account in accordance with various embodiments. As shown in FIG. 3A, a login web page may be provided by the web site when the user accesses a home page of the web site. The login web page may provide an option to “Keep me signed in.” (Not shown to simplify illustration.)

The user may enter their user identifier (e.g., username), as shown in FIG. 3B. Alternatively, the user identifier may be provided by the system when the user accesses the log in web page (e.g., where the system recognizes the client device used by the user).

The user may opt-in to use of on demand passwords instead of their user password, as described above. When the user chooses to use on demand password services, the user may specify or indicate the contact number (or email address) to be used to transmit on demand passwords to the user.

Upon returning to the login web page, shown in FIG. 3C, the system may provide a message notifying the user that their account uses on demand passwords. In some embodiments, the system may provide such a message when the user attempts to enter characters in the “Password” input box of the login web page. The user may request an on demand password by submitting a password request. In some embodiments, the login web page may provide an input features such as a button that enables a password request for the user identifier to be submitted to the system. In this example, the web page presents a “Send my password” button that may be clicked or otherwise selected by the user.

FIG. 3D illustrates an example graphical user interface that may be provided by the system via the client device in response to the submission of a password request. More particularly, the graphical user interface of FIG. 3D may provide a message indicating that the on demand password has been sent. In addition, the graphical user interface may provide an input feature for submission of the on demand password to the system. The graphical user interface may also indicate the manner in which the on demand password was transmitted. As shown in this example, the graphical user interface may provide a message notifying the user that the on demand password was sent via text and identify the mobile phone number that was used to transmit the text message. Thus, the message provided by the system via a graphical user interface may facilitate retrieval of the on demand password by the user.

The system may provide an option for requesting that the system resend the on demand password to the user. For example, a graphical user interface may provide a button such as that shown in FIG. 3E that enables the user to request that the system resend the on demand password. The graphical user interface may also provide an option for requesting that the system generate and send a new on demand password to the user. This may be desirable, for example, where the previous on demand password sent to the user has expired.

In some embodiments, a graphical user interface such as that shown in FIG. 3F may request that the user wait a particular period of time before trying to request that the system resend the on demand password or a new on demand password.

Upon receipt of the on demand password, the user may use the on demand password to log in to the user account. For example, the user may receive a text message including the on demand password and enter the on demand password via the input feature, as shown in FIG. 3G.

The user may enter the on demand password to log in to the user account, as shown in FIG. 3H. If the user enters the incorrect password, the user may attempt to submit the on demand password again.

In the example described above, the input feature via which the on demand password is submitted is presented via a web page that is separate from the login page. However, in accordance with other embodiments, the on demand password may be submitted via a login web page such as that shown and described with reference to FIGS. 3A-3C. Thus, the web page via which an on demand password is submitted may also display the user identifier. Alternatively, the system may obfuscate the user identifier that is presented. For example, the user identifier may be concealed, at least in part, on client devices that the user is using for the first time (e.g., in association with the user account). In this manner, the system may protect the user's identifier from being displayed publicly during the login process.

Network

A network may couple devices so that communications may be exchanged, such as between a server and a client device or other types of devices, including between wireless devices coupled via a wireless network, for example. A network may also include mass storage, such as network attached storage (NAS), a storage area network (SAN), or other forms of computer or machine readable media, for example. A network may include the Internet, one or more local area networks (LANs), one or more wide area networks (WANs), wire-line type connections, wireless type connections, or any combination thereof. Likewise, sub-networks, such as may employ differing architectures or may be compliant or compatible with differing protocols, may interoperate within a larger network. Various types of devices may, for example, be made available to provide an interoperable capability for differing architectures or protocols. As one illustrative example, a router may provide a link between otherwise separate and independent LANs.

A communication link or channel may include, for example, analog telephone lines, such as a twisted wire pair, a coaxial cable, full or fractional digital lines including T1, T2, T3, or T4 type lines, Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless links including satellite links, or other communication links or channels, such as may be known to those skilled in the art. Furthermore, a computing device or other related electronic devices may be remotely coupled to a network, such as via a telephone line or link, for example.

Content Distribution Network

A distributed system may include a content distribution network. A “content delivery network” or “content distribution network” (CDN) generally refers to a distributed content delivery system that comprises a collection of computers or computing devices linked by a network or networks. A CDN may employ software, systems, protocols or techniques to facilitate various services, such as storage, caching, communication of content, or streaming media or applications. Services may also make use of ancillary technologies including, but not limited to, “cloud computing,” distributed storage, DNS request handling, provisioning, signal monitoring and reporting, content targeting, personalization, or business intelligence. A CDN may also enable an entity to operate or manage another's site infrastructure, in whole or in part.

Peer-to-Peer Network

A peer-to-peer (or P2P) network may employ computing power or bandwidth of network participants in contrast with a network that may employ dedicated devices, such as dedicated servers, for example; however, some networks may employ both as well as other approaches. A P2P network may typically be used for coupling nodes via an ad hoc arrangement or configuration. A peer-to-peer network may employ some nodes capable of operating as both a “client” and a “server.”

Wireless Network

A wireless network may couple client devices with a network. A wireless network may employ stand-alone ad-hoc networks, mesh networks, Wireless LAN (WLAN) networks, cellular networks, or the like.

A wireless network may further include a system of terminals, gateways, routers, or the like coupled by wireless radio links, or the like, which may move freely, randomly or organize themselves arbitrarily, such that network topology may change, at times even rapidly. A wireless network may further employ a plurality of network access technologies, including Long Term Evolution (LTE), WLAN, Wireless Router (WR) mesh, or 2nd, 3rd, or 4th generation (2G, 3G, or 4G) cellular technology, or the like. Network access technologies may enable wide area coverage for devices, such as client devices with varying degrees of mobility, for example.

For example, a network may enable RF or wireless type communication via one or more network access technologies, such as Global System for Mobile communication (GSM), Universal Mobile Telecommunications System (UMTS), General Packet Radio Services (GPRS), Enhanced Data GSM Environment (EDGE), 3GPP Long Term Evolution (LTE), LTE Advanced, Wideband Code Division Multiple Access (WCDMA), Bluetooth, 802.11b/g/n, or the like. A wireless network may include virtually any type of wireless communication mechanism by which signals may be communicated between devices, such as a client device or a computing device, between or within a network, or the like.

Internet Protocol

Signal packets communicated via a network, such as a network of participating digital communication networks, may be compatible with or compliant with one or more protocols. Signaling formats or protocols employed may include, for example, TCP/IP, UDP, DECnet, NetBEUI, IPX, Appletalk, or the like. Versions of the Internet Protocol (IP) may include IPv4 or IPv6.

The Internet refers to a decentralized global network of networks. The Internet includes LANs, WANs, wireless networks, or long haul public networks that, for example, allow signal packets to be communicated between LANs. Signal packets may be communicated between nodes of a network, such as, for example, to one or more sites employing a local network address. A signal packet may, for example, be communicated over the Internet from a user site via an access node coupled to the Internet. Likewise, a signal packet may be forwarded via network nodes to a target site coupled to the network via a network access node, for example. A signal packet communicated via the Internet may, for example, be routed via a path of gateways, servers, etc. that may route the signal packet in accordance with a target address and availability of a network path to the target address.
